APPARATUS FOR WASHING THE FUMES OF SULPHUR.

SPECIFICATION forming part of Letters Patent No. 433,534, dated August 5, 1890. Application filed May 17, 1890. Serial No. 352,177. (No model.)

I the clarification of cane-j nice and in the manufacture of sugar, for the purpose of freeing the said fumes from sulphurous acid; and it has for its objectto construct an apparatus of this class which shall be simple in construction and efficientin operation, and which shall be able to operate automatically and continuously for a considerable length of time without requiringf urther attention than to supply the burner with the sulphur from which the fumes are derived.

WVith these ends in View theinvention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side View of an apparatus embodying our improvements. Fig. 2 is a sectional View of certain parts of the apparatus. Fig. 3 is a detail sectional View taken on the line 3 3 of Fig. 2. Fig. 4 is a sectional detail View of the cap 22 detached.

Like numerals of reference indicate like parts in all the figures.

Upon a suitable platform 1 are supported the tanks that are designated, respectively, by 2 and 3, and the burner 4. The latter, which is of ordinary construction, has the escape-pipe 5, which is connected by the lateral branch 6 with a T-coupling 7, through which extends the lower end of the pipe 8, having a valve or cook 9. The upper end of the pipe Sis connected with a pipe 10, through which water is supplied to the apparatus. The lower end of the T-couplin g is connected with a pipe 11, which extends downwardly through the cover of the tank 2 and termi nates about midway in the latter.

12 designates a siphon, one end of which is connected with the cover of the tank 2, and

the other end of which extends downwardly through the cover of the tank 3 and ter1ni nates about midway in the latter. The top of the siphon is provided with cap 13, through which extends one end of the pipe 14, having a valve or cook 15. The upper end of the pipe 14 is connected with the water-supply pipe 10. In the, cap 13, below the inlet-pipe 14, is located a perforated shield or strainer 16, through which the water from the inlet-.

pipe 14 is discharged into the siphon in numerous small jets. To the top or cover of the tank 3 is secured the outlet-pipe 17, through which the purified fumes may escape and are carried to the point where they are to be used.

Through the bottom of the tank 2 extends a vertical pipe 18, the upper end of which is on the level of the desired overflow-line, and the lower end of which extends into a receiving-vessel 19. Through the bottom of the tank 3 extends a pipe 20, the lower end of which is bent upwardly, as'shown at 21, and the upper end of which is provided with a cap 22. The bent lower end of the pipe 20 forms a trap or seal which prevents the contents of the tank 8 from escaping until the top of the cap 22 has been reached. The pipe 20 then acts a siphon to cause the escape of the contents of the said tank 3 until the level of the lower end of the cap 22 has been reached.

The operation of ourinvention will be readi1 y understood from the foregoing description, taken in connection with the drawings hereto annexed. The sulphurous fumes passing from the furnace or burner 4 through the escape-pipe 5 6 are first subjected to the action of the water supplied through the pipe 8, by means of which a draft is also created, carrying the said fumes into the tank 1. To the end of the siphon 12, which is connected with the cover of the tank 2, is connected asteampipe 24, by means of which a draft is created in said siphon, carrying the partially-washed fumes from the tank 2 over into the tank 3. On the passage through the siphon the fumes are exposed to the purifying agency of the water supplied through the pipe 14 and strainer 16. From the tank 3 the perfectlypurified fumeseventually escape through the pipe 17. The sulphurous acid which is removed from the fumes by the process of washing sinks to the bottom of the tanks and may eventually be removed. The water-supply is constant and the water is prevented from rising to too great a height in said tanks by the action of the automatically-operating escape-pipes arranged as herein described.

Having thus described our invention, We-

-1neans for supplying the sulphurous fumes and Water to said tank, an escape-pipe extending vertically through the bottom of the tank, and a receiving-vessel, said escape-pipe being extended into and nearly to the bottom of said receiving-vessel, which forms a seal for the contents of the tank, substantially as set forth.

3. In an apparatus for washing sulphurous fumes, the combination, with thetanks, of a siphon having one end connected to the top of one of the tanks and the other end extended through the top of the other tank, a cap arranged at the top of the siphon and having the Water-inlet, and a steam-pipe connected with the end of the siphon, which is connected with the top of one of the tanks, substantially as set forth.

4:. The combination of the tanks, the siphon, the cap having the water-inlet and strainer, and the steam-pipe, substantially as set forth.

5. The combination, with the tank 3, of the escape-pipe having its lower end bent upward to form a trap or seal, and the cap secured at the upper end of said escape-pipe, substantially as and for the purpose set forth.

6. In an apparatus for washing sulphurous fumes, the combination of the burner, the tanks, the pipeconnecting the burner with one of the tanks and extending into the latter, the water-inlet pipe extending into the said fume-inlet pipe, the siphon connecting the tanks, the cap arranged at the top of the siphon and having the valved water-inlet and strainer, the steam-pipe connected with the siphon, the discharge-pipe connected with the tank into which the siphon extends, the vertical dischargepipe extending through the bottom of the receiving-tank and into a receiving-vessel placed underneath, and the escape-pipe extending through the bottom of the discharge pipe and having its lower end bent to form a trap or seal and provided with a cap at its upper end, substantially as set forth.

In testimony that we claim-the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
